Census Division is responsible for conduct of Census Operations once in
tne years under the legal authority of the Census Act, 1948 and the Census
(Amendment) Act, 1993. The Directors of Census operations co-ordinate the
work of census taking in the respective States/Union Territories. The last
decennial population Census of India was during 9th–28th February 2001
with a revisional round during 1st-5th March, 2001.
All matters relating to Census including planning, pre-testing of
questions/ schedules, conduct of census, tabulation from census data and
its dissemination are dealt with in this Division.
The population census in India is conducted once in ten years. The
Census of India 2011 will be fifteenth census in the continuous series from
1872, the seventh after independence and the second census of the third
millennium. The work relating to the 2011 census has already commenced.
The Census Operations in India have been carried out in two phases;
i) Houselisting and Housing Census and ii) Population Enumeration. During
Houselisting and Housing Census phase, buildings and structures,
residential, partly residential or non-residential are identified and listed
systematically. This helps to prepare a complete and unambiguous frame for
the Population Enumeration. Housing Census in India provides statistics on
housing stock, availability of basic amenities in each household and
condition of human settlements. This information helps in assessment of
housing deficit, besides overall quality of dwellings and people living therein.
The Population Enumeration follows the Housing Census within a gap of six
to eight months which counts each and every person in the country, Indian
national or otherwise, along with her/his individual particulars and
information on social, cultural, demographic, economic and other aspects.
Planning of various phases of the census involve choosing among
several alternative procedures. It has been the practice to undertake pre-test
of census schedules about two years prior to the conduct of the census.
Based on the experience of data capturing and data processing in
2001 census using the Intelligent Character Recognition (ICR) technology,
action has been initiated to scout the latest innovations in ICR for achieving
higher degree of efficiency in capturing and processing of data. For direct
data capture in the field, specifications of handheld devices have been
finalised. The other technical details along with the potential for their
adaptation in the fields are being studied.
